Substance use disorders and cooperative research on addictions: Spanish approach as a model

Abstract

Substance use disorders (SUD), also named addiction when it is severe, is a chronic brain disorder with serious impact on individual who suffer, the public health and with high burden of disease. They are multitude of mechanisms/factors involved in addiction: from individual characteristics of the person (from genetic to impacts of stress, sex, and age) to social and environmental situation (availability and accessibility of substances, cultural and legal aspects, socio-economical situation) and type of substance of use (pharmacological characteristics) Then, research on Addiction must include different, complementary, and translational perspectives. In this review, we explore the neurobiological, psychosocial, and epidemiological knowledge of substance addiction, and the main role played by pharmacology in the research in this field. In Spain, since 2002, collaborative networks have emerged for comprehensive research on addictions, with the creation of the Addictive Disorders Network (RTA), currently redefined as the Research Network for Primary Care in Addictions (RIAPAd) with the support of the Carlos III Health Institute (Instituto de Salud Carlos III). Basic (including neuropharmacology and behavioral pharmacology), clinical and epidemiological research groups stand out, combining efforts to address prevention, early detection and treatment through interdisciplinary cooperation and the subsequent dissemination of results.
